To all whom it may concern:

Be it known that l, WALLACE VR. Bioiironn, of 1"'Taltham, in the countyof Middlesex and State of Massachusetts, have vinvented certain new anduseful lmprovements'in Holders for Frameless Mirrors, &c., of which thefollowing is a specification.

This invention has for its Vobject to plrovide improved means forbackingand holding a flat article of substantially rectangular form, such as aplate of glass adapted to serve as a mirror, the construction of theVholder being such that it iirinly4 engages the plate at dilferentportions of its margin, affords a `strong and stable Vsupport for the.

just'ed to plates of different sizes.

The invention consists lin the improved holder which 1 will now proceedto describe and claim. l

Gf the accompanying drawings', forming a part of this specification,ligure 1 represent-s a view of the back` of mirror plate provided with aholder embodying my invention. 2 represents-a Section on line 2 2 ofFig. 1. Fig. 3 represents a view of a pors tion of the front "of themirror, and corresponding portions of the holder. Fig. i represents aperspective view of one of the bars of which the holder is composed.

The same reference characters indicate the same parts in all thefigures. f y In the drawings, 12 represents a rectangular plate, whichmay be of heavy plate glass prepared as usual fornse as a mirror, by asuitable coating applied tothe lback of the plate, the front side of theplate being pref'- erably provided with beveled marginal faces 13.

uIn Vcarrying out my invention, provide the plate 12 with a holder`which forms a skeleton backing for Vthe plate, and is engaged with itsmargin at a plurality of points, the holder furnishing` means forsupporting the plate in position for use. The said holder is composedof'a series of bars plate in one direction, and a series of bars 15formed to extend across the back of the plate in a direction at rightangles to the bars 14, the bars of one series intersecting those of theother, and being rigidly connected thereto at the points of intersectionby screws 16.

Each bar is provided at one end with an integral hook 17 which is formedto engage one of the beveled faces 13 of the plate, and at its oppositeend with an adjustable hook 18 formed to engage the opposite beveledface 13, the adjustable hook having a shank 19 provided with slots 20which receive attaching screws 21 engaged with the body portion of thebar, the slots and screws co-nstituting means for securing theadjustable hooks 18 Vvto the accompanying bar at different adjustmentsto adapt the holder to plates of different sizes.

'1t will be seen by reference to Fig. 1 that the integral -hooks, arearranged to engage two Vadjacent edges of the plate, while theadjustable hooks are adapted to engage the other two edges of the plate.

ln assembling the parts, the plate is moved into engagement with all theintegral hooks, the adjustable hooks being loosened, and when the plateis properly seated on the integral hooks, Vthe adjustable hooks aremoved into engagement with the plate and fastened by the screws 21. Theholder is thus securely affixed to the plate, the only portions of theholder which are visible at Vthe front of the plate being the portionsof Lthe vhooks which project over the beveled faces of the plate, and inthe case of a mirror which is to be suspended by a cord, two ears 22,whichv are secured to the Shanks of the upper vadjustable hooks 18 bytwo of the attaching screws 21, said ears projecting above the upper endof the frame and havling-'orifices to engage a suspending cord.

It will be seen from the foregoing that the described holder is adaptedto be convenientlyand securely applied lto a plate, and that whenapplied, it constitutes a backing which materially protects andstrengthens the plate and affords a means for supporting the same.

23 represents a backing member which is interposed between the plate 12and the bars of the holder as a protector for the reflecting coating onthe back of the plate.

l claim:

A plate backing and grasping holder composed oftwo series of rigidlyconnected bars, the bars of one series intersecting those of the otherseries, each bar having at one end v,an integral hook and at itsopposite end an adjustable hook, and Ineens for securing the Intestimony whereof have axed my att-n' tdelient aldjustrnents, theintegral signature, in presence of two W'nesses.
